159493 (2000 UA) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2000 UA as potentially hazardous because its orbit does not bring it close to Earth.
2000 UA orbits the sun every 1,300 days (3.56 years), coming as close as 1.54 AU and reaching as far as 3.12 AU from the sun. 2000 UA is about 3.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of 2000 UA has been observed. It completes a rotation on its axis every 14.52 hours.
2000 UA's orbit is 0.72 AU from Earth's orbit at its closest point. This means that there is a very wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2000 UA's orbit is determined by observations dating back to Feb. 23, 1987. It was last officially observed on May 10, 2023. The IAU Minor Planet Center records 1,816 observations used to determine its orbit.
